The government described in the question is a democratic government. In a democratic government, each adult citizen is given the right to vote and each vote holds equal value. This means that regardless of a person`s social status or wealth, every citizen`s vote carries the same weight in the decision-making process.

Option 1, autocratic government, is not the correct answer as in an autocratic government, the power to make decisions lies in the hands of a single ruler or small group of individuals, and citizens do not typically have equal voting rights.

Option 3, aristocratic government, is also not the correct answer as in an aristocratic government, political power is held by a privileged upper class, often determined by birthright, and not every citizen has an equal voice in decision-making.

Option 4, plutocratic government, is not the correct answer either. A plutocratic government is one in which the wealthy class holds the most power and influence, based on their economic status. In such a system, not every citizen`s vote carries equal value.

Therefore, the correct answer is option 2, democratic government.
